You are in a statistical minority as a anallophilic crossdresser. Most crossdressers are heterosexual. Your motivation for crossdressing may be driven by the undirected nature of your sexuality, as a way to more fully explore the Male gender role.

Interesting, especially considering I don't have doubts about my gender identity. Cross dressing? Not unless you consider jeans and a t-shirt as cross dressing....I have no real interest in it for myself. *shrug*
